Use ContactLevel to Limit Google Search Traffic to ICP Users Only
When you have a tight budget and every click matters, constrain your search campaigns to high-fit buyers only. Block irrelevant traffic from ever seeing your search ads.
Without ContactLevel
You're bidding on broad, competitive, high-CPC keywords. You need to reach buyers, but most of your spend is going to noise—students, consumers, small companies. You can't afford to cast a wide net.
With ContactLevel
ContactLevel lets you create inclusion audiences based on firmographics, industry, job titles, and headcount. You draw the box, and Google stays inside it—only showing ads to pre-qualified ICP users.
How It Works
Build Your ICP Audience
Define your ideal buyers using firmographic filters: target industries, mid-market and enterprise company sizes, titles that influence or own purchasing decisions. Then sync to Google.
Apply as Inclusion in Search
In your Google Ads campaign, under audiences, target only your synced ICP audience. This restricts ad serving to qualified users only.
Adjust Campaign Settings
Because inclusion audiences are usually small, you may run into delivery issues. Use broad match keywords or optimize for clicks instead of conversions to improve reach within your constrained audience.
Monitor Performance Closely
Expect lower volume and higher CPC—but better quality and ROAS. Run the audience in observation mode first to see the impact before fully committing.
Why It Works
Why broad-match Google Search burns B2B budget
Google's broad match expanded so far in 2023-2024 that "marketing automation software" matches "automate my home thermostat." Fine for B2C. Wasteful for B2B SaaS at $30-80 CPC.
Even with phrase or exact match, Google Search shows your ad to anyone who types your keyword. Students researching the category. Job seekers looking at companies. Competitor analysts. Other marketers doing competitive research. Your sales team Googling "what's our top competitor doing." None of them buy.
The result: Google reports 10,000 clicks at $40 each = $400k spent. Marketing reports 50 SQLs. CAC = $8,000. Sales blames the leads. Marketing blames the keywords. Nobody blames the targeting layer because there isn't one.
How Google search inclusion works with ContactLevel
Search inclusion = you only run Search ads to people on your ICP Customer List.
Setup:
- Build the ICP audience in ContactLevel (VPs and Directors at companies in your verticals, 50-5,000 employees)
- Sync to Google Ads as a Customer List with 70-90% match rate
- On your Search campaigns, add the Customer List as Audience → Targeting (not Observation)
- Same keywords, same ad copy, same landing page. But the campaign only delivers to your matched audience.
The math:
→ Without filter: 1,000 clicks at $50 = $50,000 spend, 50 SQLs, CAC = $1,000 → With ICP filter: 200 clicks at $50 = $10,000 spend, 30 SQLs (higher SQL rate because audience is qualified), CAC = $333
Same SERP positions. 80% less spend. 5x lower CAC.
This is the play that pays for ContactLevel within the first month for most B2B SaaS teams. The Search budget that was burning on bad leads now goes to qualified clicks only.
When to use this play
Run search inclusion when:
→ Your Search campaigns produce junk leads (high form fill, low SQL rate) → Your CPCs are $30+ → Your ICP is identifiable (you can list job titles, company sizes) → Your TAM has at least 1,500 ICP-fit contacts
Skip search inclusion when:
→ You're a category leader and almost all searchers are buyers (rare) → Your TAM is under 1,500 (Customer Match won't activate) → Your CPCs are already low (under $5). The math is less compelling.
Frequently asked questions
What's the difference between "Targeting" and "Observation" mode?
Targeting mode restricts campaign delivery to the audience. Observation mode is bid-only — Google still shows ads to everyone but bids differently for the audience. For ICP filtering, you want Targeting mode. Observation just adjusts bids.
Will my impression share drop?
Yes, dramatically. That's the point. If you're going from "anyone Googling marketing software" to "ICP-only," impression share drops 80-95%. The remaining impressions are from your actual buyers.
Should I keep separate broad campaigns?
Optional. Some teams run two Search campaigns: one with ICP filter (high quality, low volume) and one without (high volume, lower quality, used to identify new ICP-fit contacts who weren't in the original list). Most teams just run the filtered one and call it done.
How does this affect my Quality Score?
Minimally. Quality Score is keyword-relevance and CTR-based. Narrowing the audience may slightly improve CTR (more qualified clickers) which slightly improves Quality Score over time.
Can I exclude existing customers from search inclusion?
Yes, and you should. Add your customer list as an Excluded Audience in addition to the ICP Customer List as a Targeting audience. Now the campaign only shows to ICP-fit prospects who aren't already customers.
What happens to the prospects who fit my ICP but aren't in my Customer List?
They don't see your ad through this campaign. To capture them, build a separate "Demand Gen" campaign with broader targeting (Demand Gen audiences, video) to introduce the brand, then add their data to your Customer List once they engage.
